Tuam Tshoj Kub Kub Kev Pabcuam ASTM A106 A53 Gra / API 5L Grb / A179 A192 Thick Wall / Nyias Phab Ntsa Carbon Seamless Steel Tube / Galvanized Yeeb Nkab
Txheej txheem cej luam
Peb sim ua kom tau zoo, txhawb nqa cov neeg siv khoom, vam tias yuav dhau los ua pab pawg kev koom tes saum toj kawg nkaus thiab tus thawj tswj hwm kev lag luam rau cov neeg ua haujlwm, cov chaw muag khoom thiab cov neeg siv khoom, paub txog qhov tsim nyog thiab kev lag luam txuas ntxiv rau Carbon Steel Seamless Tube / Yeeb Nkab, Tsis tas li ntawd, peb ruaj khov ua kom zoo thiab Tus nqi pheej yig, thiab peb kuj nthuav tawm cov tuam txhab OEM zoo rau ntau lub npe nrov ntsib kev sib tw ua lag luam thoob ntiaj teb, peb tau tsim lub hom phiaj tsim thiab kho tus ntsuj plig ntawm "kev pabcuam tib neeg thiab kev ncaj ncees", nrog rau lub hom phiaj kom tau txais kev lees paub thoob ntiaj teb. thiab kev tsim kho kom ruaj khov.
ASTM A106 GR. B Seamless steel yeeb nkab muaj kev vuam zoo. Vim yog cov ntsiab lus C tsawg, feem ntau tsis muaj qhov hnyav hnyav vim vuam, thiab cov welded sib koom ua ke muaj cov yas zoo thiab tawv. Tag nrho cov txheej txheem vuam tuaj yeem tau txais kev txaus siab vuam sib koom ua ke yam tsis muaj kev ntsuas tshwj xeeb.
ASTM A106 GR. B thiab 20 # zoo sib xws hauv cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab thiab feem ntau hloov pauv rau ib leeg, tab sis qhov sib txawv muaj nyob, tshwj xeeb tshaj yog hais txog kev siv txuas ntxiv.Piv txwv li, noj 20# ua piv txwv, GB50316 qhia tias qhov kev ua haujlwm yam tsawg kawg nkaus. ntawm GB8163 20# steel tube yog -19 ℃, thaum ASMR B31.3 teev tias qhov tsawg kawg nkaus kub ntawm A106 GR. B steel tube yog -29 ℃, thiab muaj qhov xwm txheej tsis muaj kev cuam tshuam kev sim.Txawm hais tias muaj qhov sib txawv ntawm cov qauv tsim, qhov sib sib zog nqus yog vim qhov sib txawv ntawm kev tswj qib ntawm Mn cov ntsiab lus.Cov chaw tsim khoom yuav tsis paub txog cov kev txuas ntxiv no. , tab sis tus neeg yuav khoom yuav tsum paub txog cov kev sib txawv no thiab qhia rau cov chaw tsim khoom ntawm cov kev xav tau thaum lub sijhawm yuav khoom, txwv tsis pub muaj teeb meem tshwm sim raws li cov cai nruj dua.
